IMPROVEMENT IN ROTARY STEAM-ENGINES.

Specification forming part of Letters Patent N 0; 47,75 1, dated May 16, 1865.

To all whom it may concern.-

Be it known that we, John W. SIMONTON and OLWIN TISTRUBLE, of Taylorsville, in the county of Bartholomew and State of Indiana, haveinvented a new Rotary Steam Engine; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making. a part of this specification, in which- Figure l is a longitudinal sectional view; Fig. 2, a perspective view; Fig.3, a plan elevation of cylinder-head; Fig. 4, a perspective view of steamchest valve, and Fig. 5 a sectional view of cylinder-valve.

First. Fig. 1 represents a longitudinalseetional view of the engine oomplete,.in which A, B, and 0 represent the three chambers of the steam-chest, the central one, A, being constructed to receive the steam from the boiler,

(not'represented,)'and the extreme ones, B and O, for the escapement of the steam after passing the revolution of the cylinder. E and G are orifices for conducting the steam from the steam-chest-A into the circular cavity between the rim and cylinder I N, F and H are orifices for the escapement of the steam.

D D is a sliding valve on the bottom of the steam-chest, with an orifice, E. R R is a pro-- jecting steam-head secured tothe rim .V V. S S isa solid cylinder (or piston) revolving on a central shaft, M, slotted on opposite sides, so

as to receive the valves K K, and P P the base of the engine.

Second. Fig. 2 represents a perspective view of the. engine closed, except at the top, in which A B 0 represent the threechambers of the steam'ohest, and D the shaft on which the cylinder revolves, and E E the base of the engine.

Third. Fig. 3 represents a plan elevation of cylinder-head, in which A represents the orifice in which the cylinder-shaft moves; B B the eccentric permanently attached to and projecting from the cylinder-head.

Fourth. Fi g. 4 represents the sliding valve at the. bottom of steam-chest, with a rack, D D,

and cog-wheel 0, attached to-the edgeor rim for its movement; B, the orifice in the valve.

Fifth. Fig. 5 represents the cylinder-valve, of which A is the race; D D, arms fitting the slot in the cylinder; B B, slots in the arms of the valve to receive the eccentrics on the cylinder-head. v

The operation of the engine is descrihed as follows, reference being had to Fig. 1 for illustration: The steam being admitted into the central chamber of the steam-chest, it passes through the orifice E on to the cylinder 38, striking the valve K, which being thrown out to the rim by means of the eccentrics, immediately but gradually after passing the steamhead R R, the cylinder is driven around under a full head of steam until the second or upper valve reaches the steam-head,where, by a gradual withdrawal, by means of the eccentrics, it passes under the steam-head, and. is in turn projected, by means of the eccentrics, to strike the rim at the point 0, where it receives a full head of steam, and is alike driven around until the first valve reaches the point Q, where it begins to recede, permitting the steam to Iescape through the orifice F ;into' the chamer B. To reverse the motion of the engine, the valve D D, by means of the rack and cog, Fig. 4,

is thrown from left to right until the orifice E communicates with the orifice. G, closing the orifice F and opening the orifice H, thus securin g a direct re verse motion without any change of prinoipleor machinery.

What we claim. as our invention, and desire to secure by Letters Patent, is-- v 1. The combination of the-'reversing-valve D D with the abutment R It, having inductionports through it, substantially as described.

2. The arrangement of the chamber (0, A, and B and the -eduction-passages H and F, substantially as shown and described.
